The MINERvA(6) experiment is designed to perform precision studies of
neutrino-nucleus scattering using nu(mu) and (nu) over bar (mu)
neutrinos incident at 1-20 GeV in the NuMI beam at Fermilab. This
article presents a detailed description of the MINERvA detector and
describes the ex situ and in situ techniques employed to characterize
the detector and monitor its performance. The detector is composed of a
finely segmented scintillator-based inner tracking region surrounded by
electromagnetic and hadronic sampling calorimetry. The upstream portion
of the detector includes planes of graphite, iron and lead interleaved
between tracking planes to facilitate the study of nuclear effects in
neutrino interactions. Observations concerning the detector response
over sustained periods of running are reported. The detector design and
methods of operation have relevance to future neutrino experiments in
which segmented scintillator tracking is utilized. (C) 2014 The Authors.
